CPU "Nocona"

Eu estava a vasculhar umas coisas e dei com este cpu para servidores e chama-se Nocona.

Não deve ser grande novidade para os mais atentos, mas chamou-me a atenção.

Isto quer dizer que nomes como: Athlon Whillemet Duron Nocona, podem aparecer na mesma frase. O que é muita giro e pode pode ser discutido mais à vontade no www.chupa-mos.com.:joker: :fart: :D
São coisas destas que tornam a informatica tão divertida.

EDIT
Nome alterado e revisto. Antes era Nacona e tinha mais piada, mas prontos.....:005:

The Register disse:
Lindenhurst has been designed for two-way servers, Twin Castle for four-way machines. They will work with processors codenamed Nacona and Potomac, respectively. Both chipsets will support PCI Express, the next-generation PCI bus designed to replace PCI, PCI-X and AGP.

Citei o que vi no site: http://www.theregister.co.uk/content/3/30649.html

Edit
Lá dizem que é um chipset a ser usado com o Nacona, tou a perceber alguma coisa mal?
 
Sendo assim vou mudar o titulo, ao menos tentar, e remendar o que está torto.

Ainda está para sair mas até já existe maneira de arrefecer os Nocona's

Bem, sempre se pode aproveitar a thread para alguma info.

Documentação "64-bit Extension" da Intel:
http://www.intel.com/technology/64bitextensions/index.htm?iid=techtrends+spotlight_64bit

• Architectural support for 64-bits of linear address; however IA-32 processors supporting 64-bit extension technology may decide to implement less then 64-bits, see Section 1.3.3.3.and Section 1.5.2.
• Register extensions accessible through a set of new opcode prefixes (REX)
• Existing general purpose registers are widened to 64-bits (RAX, RBX, RCX, RDX, RSI, RDI, RBP, RSP)
• Eight new general purpose registers (R8–R15)
• Eight new 128-bit streaming SIMD extension (SSE) registers (XMM8–XMM15)
• A 64-bit instruction pointer (RIP)
• A New RIP-relative data addressing mode
• Can use flat address space with single code, data, and stack space
• Extended and new instructions
• Physical address support greater than 64 GB; however the actual physical address size of IA-32 processors supporting 64-bit extension technology is implementation specific.
• New interrupt priority control mechanism

Mais uns pormenores:
Intel will deliver in the middle of the year Nacona, a 64-bit Pentium 4 Xeon processor geared for two-way servers. Later in the year, it will release a 64-bit version of Prescott for high-end desktops and workstations using a single processor. Next year, Intel will release multiprocessor-capable version of its 64-bit Xeon.

Barrett went to lengths to demonstrate the Itanium line will continue to have a role, albeit primarily as a back-end processor for running applications such as large databases. His keynote included presentations from end users including Wall Street analysts Morgan Stanley saying they will use both 64-bit Xeon and Itanium systems.

Compatibilidade com "3dnow"???
Intel executives were deliberately vague about the extent to which the new Intel extensions were compatible with the AMD extensions released in 2000. However, Intel did say its Nacona processor would also include enhancements to its multimedia instruction extensions, another area where AMD and Intel have diverging chip implementations.

"This is better than 3DNow," said Mike Fister, general manager of Intel's server group, referring to the AMD multimedia extensions in Athlon and Opteron.

E por fim, a mais estranha de todas, é haver especulção de se os 64 bits da Intel serão mesmo compativeis com o Amd64 ou se não será o Windows a fazer essa compatibiliade:

“Brief examination of 64-bit Extension Technology Software Developer’s Guide shows that 64-bit extension technology from Intel is very identical to AMD64 technology in certain cases. Both technologies are based in the same general principles,” said an X-bit labs’ analyst Ilya Gavrichenkov.

Such claim definitely raises questions on compatibility between AMD64 and Intel’s 64-bit Extensions Technology.

“Compatibility with AMD 64 does not matter. What matters is compatibility with Microsoft’s operating system. Both Intel and AMD processors have unique micro-architectures so approaches may vary but both must work the OS,” an Intel’s spokesperson said.

“Intel, just like AMD, added a special CPU mode called “64-bit sub-mode”, where 64-bit flat linear addressing, 8 new general-purpose registers (GPRs), 8 new registers for streaming SIMD extensions (SSE, SSE2 and SSE3) and 64-bit-wide GPRs are available along with instruction pointers. Similar to AMD’s 64-bit chips, Intel’s 64-bit extension technology can run in either legacy IA32 mode or IA32e mode. IA-32e mode is the mode a processor uses when running a 64-bit operating system. The IA32e mode consists of two sub-modes: 64-bit mode and compatibility mode, just like it is implemented in AMD64 architecture,” X-bit labs’ analyst explains.

Intel’s officials distinctly claim that the 64-bit Extension Technology has been fully developed by Intel, even though Intel and AMD have cross-licensing agreement.
